e.r.g. 生物电场模型的数值解是利用有限差分连续过松弛技术开发的。该算法实现的差分方程适用于任何涉及轴对称的球形体积导体问题。所使用的节点网络的特点是节点之间的间距可变且不均匀，以及电导率的逐点变化。当将数值解与几个简化测试用例的解析解进行比较时，证明了出色的精度。当模拟更真实的生理配置时，该模型与从文献中获得的实验数据表现出相当好的一致性。
A numerical solution of a model of the bioelectric field of the e.r.g. was developed utilising a finited-difference successive overrelaxation technique. The difference equations implemented by the algorithms are applicable to any spherical volume conductor problem involving axial symmetry. The nodal network utilised was characterised by a variable and nonuniform spacing between the nodes and a pointwise variation of conductivity. An excellent accuracy was demonstrated when the numerical solutions were compared with the analytical solutions for several simplified test cases. When simulating the more realistic physiological configurations the model demonstrated a reasonably good agreement with the experimental data obtained from the literature.
